' The roller screen and attachment for windows,

according to this invention, comprises a housing .5 ill for attachmentupon a window sill ll of a window l2. The window I2 is of conventionalconstruction having window sashes I2 and 82 slidably supported in awindow frame in the customary manner. The housing I0 is constructed 10from sheet metal or other material and is fixedly attached uponthewindow sill H by means of lugs it. A cover it! is provided for closingthe open top of the housing i0.

A- spring roller it is mounted within the hous- :1 ing ill for rolling ascreen upon itself. The roller it is formed at one of its ends with apeg I5 rotatively supported in the said end and extending from the endof a circular housing l6 mounted overthe said end. The peg I5 is formedat its 2 outer end with a square portion l5 which engages acomplementary square opening formed in a bracket I! attached to one endwall of the housing Ill, The cooperation between the square end I! andthe square opening formed in the brackets ll limits the peg againstrotating. A means isprovided for causing the roller I4 to always returnto its normal position after having been turned out of said normalposition.

The returning means comprises a spring I8 coaxially engaged upon the pegl5 and having one of its ends engaging an opening 20 formed in the e ofthe roller II and the other of its ends engaging an opening 2| formed inthe peg it. This spring I8 is confined within the tubular .3 housing Itand is adapted to be tightened upon the peg I! when the roller isrotated in one di-v rection tor returning the roller ll to its normalposition when the said roller is released.

A screen 22 has one of its ends securely at- #9 tached to the roller M.The screen 22 is of a width to extend entirely across the .opening inthe window frame when the sash l2 is moved upwards. Binding strips 23are mounted along the edges of screen 22 and. have their free endsextending past the free end of the screen 22.. The strips. 23 aresecurely attached to the screen 22 by means of rivets 24 which extendthrough portions of the strips 22 and the screen 22. The strips" areconstructed from leather or similar material and are of channel shapeand have the edges of the screen 22 engaged between the adjav cent armsthereof.

A member an is securely attached to the free ends of the strips 22. Thismember 25 comprises a piece of channel shaped metal having the free endsof the strips 23 engaged between the arms thereof and securely attachedthereto by means of rivets 26. A means is provided for attaching themember 25 to the window sash i2 and comprises bolts 2-! engaging throughthe member 25 and threadedly engageable with nuts 28 securely attachedto the bottom edge of the window sash i2". When this member 25 issecurely attached to the window sash l2 and the window-sash is raised asshown in Fig. 1, the screen 22 will be extended from the housing iagainst the action of the spring I9. I

A roller 29 for an auxiliary section of screen is rotatively adiustablymounted between the binding strips and the top edge of the screenportion 22. The strips 23 in the vicinity of the top edgeof the screen22 are formed with enlarged portions 23 into which the ends of theroller 29 engage. These enlarged portions 23 are clearly shown in Fig.2, 3, 6 and '7. The means for rotatively adjustably supporting theroller 29 comprises a headed pin 30 engaging through an opening 3|formed on one of the strips 23 and engaging into one end of the roller29. At the other end the roller 29 is formed with a square peg 32 whichextends through a square opening 33 formed in the other strip 23, andthe portion of the square peg 32 which extends beyond the outer edge ofthe strip 23 is formed with an opening. A cotter pin 34 is adapted to bepassed for purposes of rotating the roller 29.

-means comprises elongated slots 35 formed in the through the opening,and have its free ends bent apart for preventing accidentaldisengagement oi the cotter pin and for holding the square peg inposition within the opening. i

. A means is provided for permitting the square peg to be easilydisengaged from the square openingwhen the cotter pin 34 is removedtherefrom This enlarged portion 23 of the strip 23 through which thesquare peg 32 extends so that the portion between these slots may bebent out of the plane or the remaining portion or the strip 23 todisengage the square opening from the square peg. In their separatedpositions it is possible for the roller 29 to be manually rotated.

An auxiliary section of screen 36 has one of its ends wound upon therollerand extendable upwards from the free edge of the screen 22 to themember .25. This auxiliary screen 39 is also the same width as the widthof the opening in the 'windowframe and has its edges slidably engagingthe strips 23.

A Lresilient means is connected with the top edge of the auxiliaryscreen 36 and is connected with the member 25 for holding this auxiliaryscreen in its extendedpositions. This latter means comprises tubularmembers 31 having their upper ends closed and their bottom ends.

. aligned with openings 33 formed in the top face opening betweentheifree edge of the screen 22 and the bottom edge of the member 25.When desired, the free edge of the auxiliary screen 33 may be adjustedto various positions along the opening between the screen 22 and themeni-= ber 25 for providing a small space between the v the positionillustrated by the dot and. dash linesJ25 in Fig.' 2 to enclose thescreen 22 and the auxiliary screen 36 within the housing Ill. The coverI0 is formed with an opening l3 of a sufliclent width to permit theenlarged portions 23 to pass therethrough so as to be wound upon theroller M.

The operation of this device is as follows:

The housing I 0 is secured upon the window sill l i and the member 25 issecured to the bottom edge of the bottom sash l2 by engaging the bolts21 therethrough and threadedly engaging them on the nuts 28 i'astened tothe bottom edge of the sash' l2. The screen 22 may now be extended fromtheopening I'll formed on the cover Hi by moving the sash i2 upwards.This causes the screen 22 and the strips 23 to be unwound from theroller l4 against the action of the spring l8. When the desired positionfor the sash l2 had been reached the open portion extending between thetop edge of the screen 22 and the bottom of the member 25 may be closedif desired by extending the auxiliary screen 36.

To extend the auxiliary screen 36 one must remove the cotter pin 34 fromthe opening formed in the extended end of the square peg 32. Then onesfinger nails are engaged into the slots 35 and that portion of the strip23 been closed the square peg is again engaged into the square openingand the cotter pin 32 applied thereto for holding these parts in theirinterengaged relationship. The-cooperation between the 'squarepeg andthe square opening'prevents the roller 29 from being rotated by thesprings 39 According to the modification shown in Figs. 9

and 10, the construction of the roll screen is simflar of thatpreviously described except that the construction is shown applied tothe inside of a twin window l2. A hollow casing I0 is mounted upon thewindow sill II and has two separate and distinct roll screens mountedtherein each of which is individually attached to the bottom sash ofeach window of the twin window I 2'. Likewise there, is a hollow casingH1" attached to the top of the window'frame. This housing I 0" is alsoprovided with two-separate and distinct roll screen constructions. eachof which is attached to the top edge of one of the top sashesof saidtwin window. In other respectsthis form is identical to the prior formand the same partsmay be recognized by the same reference numerals. A

According to the modification shown in Fig. 11, the construction'of the.roll 'screen is 'similarto that previously described except the hollowcasing 10" is mounted below the window sill li'. A similar screen casinglll is mounted above the top of the window frame and is provided withsuitable, doors it". The screens 22' are mounted to the window sashes I2and l2 in any suitable manner.

It is to be understood that this-screen device may be used for anysuitable purpose and at any desired location.
